Benzene is a colorless, flammable liquid with a sweet odor, which is widely used in industrial processes. It is a natural constituent of crude oil and is one of the simplest aromatic hydrocarbons. Benzene is primarily used as a precursor to heavy chemicals such as ethylbenzene, cumene, and cyclohexane, which are used to manufacture plastics, resins, synthetic fibers, rubber lubricants, dyes, detergents, drugs, and pesticides.
